firstly, one end of the climbing rope is put into the test guiding mechanism, then the two sliding blocks 3 are mutually close and contact through the action of the synchronous moving mechanism, when the two sliding blocks 3 are contacted with each other, the two semicircular rings 4 are combined to form a complete circular ring, the climbing rope is sleeved in the circular ring, a plurality of cambered surface contact blocks 6 generate certain contact extrusion with the surface of the climbing rope when the two semicircular rings 4 are combined, so that the connecting pin 5 moves along the inserting position of the semicircular ring 4, the first spring 8 generates certain compression deformation, the pressure sensor 9 sets the pressure at the moment to be a normal value, then starting the test guide mechanism, starting the test guide mechanism to enable the test guide mechanism to drive the climbing rope to move in a guide way, wherein the surface of the climbing rope is contacted with the surfaces of the cambered surface contact blocks 6 in the process of guiding the climbing rope by the test guide mechanism, when the climbing rope has a convex or soft collapse or bending and unsmooth deformation on the surface, the contact surface of the cambered surface contact block 6 and the climbing rope moves to ensure that the first spring 8 continues to compress or rebound, so that the detected value of the pressure sensor 9 is increased or decreased, and when the detected value of the pressure sensor 9 is significantly increased or decreased, the climbing rope is required to be replaced if the surface of the climbing rope has the deformation condition of protrusion, soft collapse or unsmooth bending, the moving test of the surface of the climbing rope is beneficial to preventing the abrasion and the scratching risk of hands of users due to the stroking test, and through the contact of a plurality of cambered surface contact blocks 6 and climbing rope, the omission of the surface deformation test of the climbing rope is effectively reduced, the improvement of the detection accuracy is facilitated, and the safety of using the climbing rope is ensured.
The foregoing shows and describes the general principles, principal features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are merely illustrative of the principles of the invention, but that various changes and modifications may be made without departing from the spirit and scope of the invention, which is defined by the appended claims and their equivalents.
